Rainwater and Solar Power Harvesting
SystemThe
proposed system saves all the rainwater and solar power received on the roof,
and incorporates water as an architectural design feature inside the house. "Seeing"
how much water we are saving will help us to be more conscientious about
maintaining a rational balance in our daily water use.The
proposed system has three main elements: a catchment area roof equipped
with solar panels, a transparent storage tank, displayed in the center
of the house and protected with an anti-evaporation membrane; and a water
distribution sub-system consisting of pumps, filters, and exposed pipes.
Data
-According
to the USGS calculation software, a family of 4 members consumes around 110,000
gallons of water per year inside the household.-A
square foot of roof collects 0.6 gallons per inch of rainwater. With 40 inches of rain per year, a typical 2500
SF house with a 3,000 SF roof could collect 72,000 gallons of rainwater per
year, which is 65% of the household water use.-According
to the USEIA, the average American family electricity consumption is 920 kWh
per month. That power can be produced by installing 76 solar panels of 125
watts on the roof, which would take around 900 SF.
